This series adds the ability, for crypto PMDs, to communicate the
minimum head/tailroom requirement it may have, using the existing
cryptodev_info framework.
The availability and use of head/tailroom is an optimisation if the
hardware supports its use for crypto-op info. Devices that do not
support using the head/tailroom, can continue to operate without
any performance-drop.
Cavium's OcteonTX crypto hardware supports this feature and would use
headroom and tailroom for submitting crypto-ops to the hardware.
v1:
* Removed deprecation notice and updated release notes
* Added corresponding change in test-cryptodev
Anoob Joseph (3):
cryptodev: add min headroom and tailroom requirement
app/crypto-perf: honour cryptodev's min headroom/tailroom
test/crypto: skip validation of head/tailroom used by PMD
